          Analyze these commits and generate a changelog of all notable user facing changes.

          Commits between ${previous} and HEAD:
          ${commits}

          - Do NOT make general statements about "improvements", be very specific about what was changed.
          - Do NOT include any information about code changes if they do not affect the user facing changes.
          - For commits that are already well-written and descriptive, avoid rewording them. Simply capitalize the first letter, fix any misspellings, and ensure proper English grammar.
          - DO NOT read any other commits than the ones listed above (THIS IS IMPORTANT TO AVOID DUPLICATING THINGS IN OUR CHANGELOG)
          - If a commit was made and then reverted do not include it in the changelog. If the commits only include a revert but not the original commit, then include the revert in the changelog.

          IMPORTANT: ONLY return a bulleted list of changes, do not include any other information. Do not include a preamble like "Based on my analysis..."

          <example>
          - Added ability to @ mention agents
          - Fixed a bug where the TUI would render improperly on some terminals
